2015 GMC Terrain Owner Comments

The contact owns a 2015 GMC Terrain. The contact heard an abnormal noise coming from the vehicle. The dealer diagnosed that the water pump, timing belt, gasket kit, and chain links for the timing belt failed and needed to be replaced. The vehicle was repaired. After being serviced, the vehicle later began to lunge forward and the gears attempted to shift. The vehicle was taken back to the dealer where it was diagnosed that the transmission was slipping. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 24,461.

Engine keeps shutting off while driving; would have to guide the car off the road and restart. Radio shuts off; all electrical systems shut off and car would have to be restarted. This has been happening after the car was purchased sporadically since last year. The vehicle was turned in for service on the issue, however I was informed that they found nothing wrong. Just this past week till now, the cars engine and electrical system starting shutting down again while driving or while in parking mode at least more than 6 times.

I've attached my final repair notice to GM and it has all of the details. I have since taken my car back to the dealership to have the final repair done. They still say nothing is wrong with it. I am terrified to drive my car. I asked GM to take the car back and they say they are not willing to do anything at all to help me. The transmission is jerky and the brakes barely work. Please investigate. Its like GM would like to wait until there is a huge accident and loss of life before doing anything.

2015 GMC Terrain. Consumer writes in regards to sudden loss of engine power, accelerator pedal and throttle failures. The consumer stated when she tried to accelerate, the vehicle barely moved. The consumer turned off the vehicle and re-started it, with the same results. The engine would just idle as if the accelerator pedal was disconnected.

While switching lanes in traffic ( around 15 mph), the vehicle shut off (including radio gauges and engine). Put on hazards, switched from drive to park, and restarted the car.
